1944: The Avery–MacLeod–McCarty experiment isolates DNA as the genetic material (at that time called transforming principle). [24]1947: Salvador Luria discovers reactivation of irradiated phage, [25] stimulating numerous further studies of DNA repair processes in bacteriophage, [26] and other organisms, including humans.
The history of genetics dates from the classical era with contributions by Pythagoras, Hippocrates, Aristotle, Epicurus, and others. Modern genetics began with the work of the Augustinian friar Gregor Johann Mendel .

The first known mass extinction was the Great Oxidation Event 2.4 billion years ago, which killed most of the planet's obligate anaerobes. Researchers have identified five other major extinction events in Earth's history, with estimated losses below: [11] End Ordovician: 440 million years ago, 86% of all species lost, including graptolites

This is a list of people who have made notable contributions to genetics. The growth and development of genetics represents the work of many people. This list of geneticists is therefore by no means complete. Contributors of great distinction to genetics are not yet on the list.
Genetics is the study of genes, heredity, and the variation of organisms, as well as the medical practice of diagnosing, treating, and counseling patients with genetic disorders. Humans began applying knowledge of genetics in prehistory with the domestication and breeding of plants and animals.
The LUCA probably existed at latest 3.6 billion years ago, and possibly as early as 4.3 billion years ago [2] or earlier. The nature of this point or stage of divergence remains a topic of research. All earlier forms of life preceding this divergence and all extant organisms are generally thought to share common ancestry. On the basis of a ...
